m5C Motif Atlas of SARS-CoV-2: CG, CCA, and ACW Sites Across 9.36 Million Genomes

This dataset provides a comprehensive annotation of RNA m5C-associated motifs such as CG, CCA, and ACW across 9,356,279 high-quality SARS-CoV-2 genomes (aligned to reference NC_045512.2). For each genome, we report motif counts and 1-based genomic positions. Data is aggregated into 118 chunks (grouped into 24 compressed bundles) with per-chunk and global summaries. Boundaries & Notes for Use: Motifs are identified in silico based on sequence context; not experimentally validated. Genomes are filtered for length ≥28,000 nt to exclude fragments. Positional data reflects alignment coordinates; not adjusted for indels or structural variants. Designed for population-level motif frequency analysis, not single-genome functional inference. Does not include patient metadata, geography, or time only sequence-derived features. Analysis done by: [e-mail]
